Average Weight for 17-Year-Old Girls: What's Normal?

According to the Centers for Disease Control and Prevention (CDC), the average weight for a 17-year-old girl in the United States is 140.5 pounds. However, it is important to note that this is just an average, and there is a wide range of normal weights for girls of this age. Some girls may weigh more or less than the average, and this does not necessarily mean that they are unhealthy.
